![]() Hi, i just wired up a new isolator switch, witch obviously goes to two batteries, but, the problem that i have is in the off position...I have wired the positives from both batteries to the battery No1 and battery No2 positions and the engine positive to the common on the isolator switch, the acessories go to the positive on batt 1 and the negative engine lead goes to battery 1 with a link to No2...Now by rights the acessories should come on when batt 1 is selected (and they do) but they also come on when batt 2 is selected and when it is in the off position..! Everything works on any setting on the isolator switch except the engine, which only works on the No1 battery..As far as i can see, it's wired the way of the instructions but any help would be greatly appreciated..Just want to be able to isolated the acessories for night fishing...cheers..

The switch can do nothing! you have a direct connection. and the negative engine lead goes to battery 1 with a link to No2...Now by rights the acessories should come on when batt 1 is selected (and they do) but they also come on when batt 2 is selected and when it is in the off position..! Everything works on any setting on the isolator switch except the engine, which only works on the No1 battery. I bet it also works on the 2 position! (assuming the battery is charged and capable of starting the engine) .As far as i can see, it's wired the way of the instructions but any help would be greatly appreciated..Just want to be able to isolated the acessories for night fishing...cheers.. Povman You do not say what your expected requirements are from Batt1 and Batt2. Engine start from one and Domestic supply from the other? You do not specify what you mean by accessories? I assume cabin lights etc. Assuming the above then connect accessories to common terminal (with alternator and engine start circuit.) Now with isolator off no battery connection to anything With isolator in 1 position accessories and fed from bat 1 with isolator in 2 position accessories fed from bat 2 Ignition switch assumed to be off therefore no losses that way None of the above should be taken to suggest that I advocate the use of 1,2 both switches!!!!
